Description
Technical field
the utility model relates to a kind of boiler, particularly relate to a kind ofly to increase work efficiency, reduce energy loss, the greenhouse heating stove that is extensively suitable for modernization agriculture-stock production.
Background technology
hot-blast stove utilizes air as medium and carrier, and warming-up device similar relatively in the market can improve the warming-up device of a kind of specialty of heat utilization efficiency and hot operating efficiency larger.Pot arch starts extensive use in late 1970s in China as thermal power machinery, it has become the regeneration product of electric heat source and conventional vapor power heat source in many industries, especially in modernization agriculture-stock production, significantly reduce infrastructure device to drop into, lower production management, processing of agriculture product cost, become irreplaceable warming-up device.Pot arch can be divided into heat accumulating type and heat exchange type two kinds by operation principle; Wherein heat accumulating type pot arch, divide ball pot arch by the heat storage of pot arch inside and adopt the pot arch of checker brick, can be divided into top ignition by combustion system, internal combustion type, external-burning etc. are several.The structure of pot arch is combined by combustion furnace and heat exchanger, the fuel such as fire coal can be burnt.Current pot arch of a great variety, is applied to every field.The Development Trend of those skilled in the art is all wish that pot arch can obtain required hot blast fast, if notification number is CN2516889Y, just can realize the object obtaining the hot blast needed very soon, but hot blast in air-out passage by time due to a lot of with heat exchange with outside thermal loss, cause waste, and wind distance of process in passage is short, the exchange heat of pot arch cannot be played completely.CN2516889Y is designed with coal feed point due to burner hearth side, the space major part of burner hearth between furnace shell is cut off by coal feed point assembly, and when air rotational movement, the leeward side of coal feed point produces negative pressure and forms parital vacuum, because vacuum area does not have air-flow to cool, burner hearth is easily burnt.Also reduce heat exchange efficiency simultaneously.CN2516889Y due to burner hearth structure hot blast outside, cold wind is interior, and stove table temperature is very high, and stove surface forms very high temperature difference in surrounding air, strengthens Speed of diffusion, causes energy waste.When being applied to agricultural modernization hothouse production, needing to keep comparatively remote with animals and plants, otherwise animals and plants near stove can be caused to burn, cause the underproduction or space waste.CN2516889Y because air inlet is below stove, air outlet in a furnace between, air motion path in stove is short, and heat exchange is thorough, reduces killing effect to the germ virus in ambient air.
Summary of the invention
there is provided a kind of greenhouse heating stove to solve the problems of the technologies described above the utility model, object improves heat exchanger effectiveness, extends the time of staying of wind in stove, improves the temperature of discharging hot blast, reduces thermal loss.
for reaching above-mentioned purpose the utility model greenhouse heating stove, comprise furnace shell, burner hearth is provided with in furnace shell, it is air intake down going channel between burner hearth and furnace shell, air intake data feedback channel is provided with between burner hearth and air intake down going channel bottom, air intake down going channel and air intake data feedback channel communicate in bottom, heat exchanger tube is provided with in burner hearth, air intake data feedback channel top communicates with heat exchanger tube bottom, heat exchanger tube top is stretched out roof of the furnace and is communicated with air outlet, hollow bar is provided with in the bottom of burner hearth, hollow bar one end communicates with the end of air intake down going channel, the hollow bar other end is inserted in air intake data feedback channel, coal feed point is provided with in the lower side of burner hearth, coal feed point stretches out furnace shell, roof of the furnace communicates with outlet flue, be separated by by upper spacer and air intake down going channel at air outlet, the air inlet of air intake down going channel is located at the upper side of furnace shell.
described air intake down going channel and air intake data feedback channel are separated by by division board.
described burner hearth inner casing is provided with fin.
described fin is located in air intake down going channel and air intake data feedback channel respectively.
described hollow bar one end is quarter bend.
described heat exchanger tube first stretches to burner hearth center, then stretches out to oblique upper, hearth wall direction.
it is base plate below hollow bar.
axis and the furnace shell of air inlet are tangent.
the utility model has the advantages of: cold wind is enclose hot blast by the utility model, the cold wind outside hot blast and furnace shell is made not carry out heat exchange, the hot blast that air outlet is discharged is exactly the hottest, and the cold wind in air intake down going channel is by carrying out preheating with burner hearth heat exchange, improve the temperature entering cold wind in heat exchanger tube, improve the thermal efficiency.Because cold wind enters from above, upwards enter into heat exchanger tube again after moving to bottom, add the time of staying of cold wind in stove, ensure that the time of heat exchange.Cold wind can be had between furnace shell and burner hearth to flow, prevent burner hearth to be locally melted.
